REEL FOR PAPER.

To all whom it may concern:

Be it known that 1, CHARLES E. Fern, a citizen of the United States of America, and resident of Holyoke, in the county of Hampden and State of Massachusetts, have invented certain new and useful Improvements in Reels for Paper, of which the following is a full, clear, and exact description.

This invention relates to improvements in what may be termed automatically contracting reels on which are to be wound tissue or crepe paper or other sheet material, in such manner that the members of the reel on which the convolutions of the paper are successively wound recede inwardly at each revolution proportionate to the thickness of the paper whereby the convolutions are all the same and so that when the paper on the filled reel is cut or sub-divided to make several piles of sheets suitable for napkins or other articles, they will all be of the same slze.

The invention essentially comprises in combination a rotative shaft, a frame mounted on and rotatable with said shaft, having radial guideways, a plurality of members having cam inclined edges, and a disk or other suitably sha ed part, on which said members are carrie which is loosely mounted on said shaft for a degree of revoluble movement relatively to the latter, means for imparting a variable resistance to movement of said disk, and rods movably guided in the radial ways of said frame having their inner ends engaged with the respective cam inclined members and having transverse bars, to constitute the reel, at their outer ends.

The invention furthermore com rises certain particular combinations an arrangements of parts and the constructions of parts all substantially as hereinafter fully described and set forth in the claims.

The improved reel is illustrated in the accompanying drawings, in which Figure l is a side elevation; Fig. 2 is a central vertical longitudinal section as taken on line 2-2, Fig. 1; Fig. 3 is a plan view of the left hand end portion of Fig. 1; Fig. 4 is a perspective view illustrating a detail of construction hereinafter referred to; Figs. 5 and 6 are respectively a side elevation and a central vertical section on line 66, showing a construction of the reel when made up with single, instead of double, reel bar supporting radial rods.

Specification of Letters Patent.

Application filed. July 9, 19(38.

Serial No. 442,663.

Similar characters of reference indicate corresponding parts in all of the views.

In the drawings, A represents the supporting shaft of the reel horizontally mounted in suitable journals therefor in the frame B and having at its one end a sprocket wheel C by means of which rotary movement may be imparted to the shaft through the sprocket chain D which runs around a sprocket wheel E on a shaft F to which power may be applied from a suitable source.

A sleeve G is loosely but closely fitted on the intermediate portion of the shaft A and provided at its opposite ends with circular flange-like extensions or disks H H which are provided, circumferentially, with outwardly projecting members a a having cam inclined edges 10 and radial or perpendicular backs 12, these members being in suitable number and regularly spaced.

J, J represent frames provided on end portions of the shaft in facewise proximity to said disks, one J having means for preventing endwise movement thereof which practicably may consist of a key I), while the other frame J is by its hub loosely fitted about the other end portion of the shaft and movable slightly, axially relatively to the latter. Both said frames have radial guides d d for a series of rods L L which by their inner ends have contact bearings or supporting engagements respectively with the cam inclined members a a of the said disks, and bars f are extended transversely between the ends of corresponding rods of both sets, in lines parallel with the axis of the shaft A to constitute the winding or sheet receiving members of the reel.

The left hand end portion of the shaft A is shown as constructed with a longitudinal slot 9' therethrough, through which is engaged a loose bar or key it having angularly turned ends k which engage in recesses h in the ends of the hub of the circular frame J so that while not preventing the axial movement of the part J the latter is constrained to rotate in unison with the shaft.

A screw lc,having the hand wheel t,-is threaded in an axial hole therefor, in the end portion of the shaft A, which extends into the aforementioned slot 9 so that the screw may have a forcing engagement against the bar or key It to crowd, through the latter, the frame J to a required tension relatively to the adjacent disk H and through the medium of the sleeve G to correspondingly tension the right hand disk H and frame member J. r

In practice, layers or disks j of leather, felt, fiber, or other suitable, more or less compressible and frictioning material are interposed between the disks H H and the adjacent circular shaft carried members J and J M represents an endless apron guided around sheaves or rollers m, an inner course 00 thereof having a half-circular engagement around the reel bars or slats and serving as a means for limiting or determining the maximum dimension of the winding convolutions,-no completely encircling portion of the paper wound on the reel ever being permitted to be greater than, or exceed the limitation imposed by the endless apron.

As the paper from the supply roll P runs to and is wound onto the reel, the tensioning or force of the paper in a direction inwardly or towards the axis of the reel causes gradual inward receding movements of the reel slats or bars f and their carrying rods, the inner ends of which latter are yieldingly resisted by the members a of the disks H, which members have revoluble movements slightly as the same is imparted thereto by the crowding action of the rods edgewise thereagainst.

The machine is, preparatory to being used, adjusted as to the tension or variability of yielding resistance, which the inclined member carrying disks have relatively to the adjacent shaft carried parts; and the capability of yielding resistance may be nicely predetermined or regulated to e proportionate to the winding tension of the paper on the reel so that the wound paper will never become circumferentially enlarged greater than the initial convolution, even if the restricting apron or belt N is not employed; but the provision of the belt is simple, inexpensive and conducive to the general satisfactory composition of the machine.

After a sufi icient quantity of the paper has been wound on the reel and-the machine is stopped, the wound paper is usually removed by cutting it at regular intervals and along the lengths of the slats or reel bars f for the making of paper napkins or other articles all of uniform widths.

In placing the machine in condition to be again employed for receiving a new quantity of pa er wound thereon, the sleeve G is turne for a fraction of a rotation relatively to the shaft A through means of a bar or lever inserted in one of the radial sockets 0 modified in respect of minor details and at the middle of the sleeve whereby the; cam inclined ed es of the members a force the rods L and slats f to their outermost distension.

' all intents and purposes like that shown in the other illustrations, excepting that it is matter of design for the production of a reel for winding narrower paper and where double sets of reel slat supporting rods and guides and actuators therefor are not requirrd. In this case the disk H which carries the members a having the cam inclined edges is frictionally bound and yields.

rotatively relatively to the shaft A between the face of the frame J which is keyc d or affixed on the shaft and a follower disk J which is loose on the shaft and with the hub of which the screw forced bar H is operative in a manner described in conjunction with the structure shown in Figs. 2 and 3; and in the arrangement shown in Fig. 6, disks or layers j, j of leather or like frictioning material are interposed between the opposite faces of the disk H and the parts J and J at either side thereof.
